SPECIFICATION forming part or Letters Patent No. 734,755, dated July as, 190e. Application filed February 24, 1903. `Serial No. 144,695. (No model.)

To @ZZ whom it may concern/.

Be it known that I, EDWIN M. ScHANTz, a citizen of the United States, residing at Zim-` merman, Greeneicounty, State of Ohio, have invented a certain new and useful Marking- Machine to be used, for instance, -to mark lumber to be cut up subsequently into socalled dimension stuff, andldo'declarethe following to be a clear,` full, and exact de-` scription thereof, attention being called to the accompanying three sheets of drawings, with the referencenumerals marked thereon, which form also a part of this specification.

This invention relates to a new and useful marking device, the object being to mark off for subsequent cutting rectangular pieces on larger pieces, which latter are to be divided t in such smaller pieces or from which lsuch smaller pieces are to be cut. At the same time the device shows the superficial dimensions-that is, length and widthof the sur-` face so marked off. The device consists substantially of a member Which I call marking-guide and which serves to guide a suitable marking implement, which may be a pencil or piece of chalk, while the same, held in the hand, is moved over the surface to be marked off. There is also a measuring device operatively connected-with the markingguidev in amanner that any change in the marking-guide from one position to another is immediately indicated in certain selected scaleunits-as inches, for instance-sothat the size of the piece so marked off maybe at once ascertained. As far as the operation of the entire device is concerned the material handled may be paper, pasteboard, leather, cloth,ror wood. In the present case the device `is intended for use on Wood or lumber, which is to be eutup in smaller pieces of certain sizes or so-called dimension-stuft,7 and which pieces are to be marked off by my device prior tol such reduction. y The device may be used in two Ways. One

wayto use it would be formarking pieces ac cording to certain fixed sizes given and in which casethe marking-guide would be set correspondingly to the size given and as i-ndicated by the measuring device. In the other way the position of the marking-guide `would be governed by other circumstances-- as, for instance, by the condition of the material, as to quality or defects in it, and where the marking-.guide would-,be set with respect to these circuinstances-while the matter of dimension would be a subject of subsequent consideration. Thus, for instance, in the more 'speciiic object for which this device has been designed and which is to mark off pieces free of defects--as,for instance, in lumber pieces clear of knotholes-the markingguide is first set and used, the size of the markedotf area being subsequently ascertained. The device has` been constructed with` a View to more particularly satisfy requirements for this lastmentioned manner of use, since the means and construction rethe accompanying three sheets of drawings,

in Whichquired in such. case will also be available to Figure l is a front View of the device. Fig.

2 is a topview of the same. Y Fig. 3 is a side view of it. Fig. 4 is a vertical cross-section of the machine. Figs. 5 and 6, in views similar to Fig. 2, but at reduced scale, illustrate manner of using the device. Fig. 7at enlarged scale, shows one end of the measuringdrum; `and Fig. 8 is a cross-section thereof.

10 is a suitable table on which the material to be marked for subsequent,` subdivision is supported, the material beingwood or lumber, and is indicated by 1l.` This table is supported on a base 12, on which it maybe moved back and forth. This movement may be a sliding one, but is preferably onrollers 13, moving on tracks 14E. vStops or a lip 15 projects up from this front edge of the table, against which -the edge of` the board ll` is placed, so as to have this latter supported parallel to its movement.

The most important marks to be put down as indicating lines for subsequent separation are those defining positions of lines of division or cuts in a longitudinal direction, since these lines are usually the longest. For marking these lines I use what may be called a movable ruler,or, as before defined, a mark- IOO . of lip 15.

ing-guide, (indicated at 16,) and which is used to guide a' pencil, piece of chalk, or other marking implement while held in the hand and passed along such ruler or guide. The same is supported in a manner that it may be moved or adjusted between the longitudinal edges of the board to be marked for subdivision, the support being such that said- 'ruler or guide in all its positions or movements for adjustment is held strictly parallel to said longitudinal edges of the board or For such purpose it is provided with two rearwardlyextending branches or arms 17, each of which on its outer side has a flange 18, fitted into a guideway 19, cut in the inner sides of standards 21, one at each fend of the machine.

ingguide is operatively connected with ay meas u'ring device which, preferably in inches, indicates the distan ce between such longitudinal lines which, in other words, is equivalent to the width of the pieces marked off. This measuring device consists of a drum 22, having its face divided circumferentially by lines indicating inches or fractions thereof. The rotation of this drum is made dependent on the movement of ruler 16, for which purpose one, but preferably both, ends of this drum are provided with cog-wheels 23, which are engaged by toothed racks formed in the upper edges of arms 17. The drum and its cog-wheels are supported in standards 21. It will now be seen that the rotation of the drum is proportional to the movement of ruler 16, and therefore if this latter has been moved from its initial positionv (shown in Fig. 3) and to a position, say, about four inches farther out, as shown in Figs. 4 and 5 and in dotted lines in Fig. 2, a section of board four inches wide may be marked off for subsequent cutting, ruler '16 being used to run the division line and the measuring-drum will show four inches. For running the next line ruler 16 will have to be pushed into its initial position, whereby also the drum is returned to zero. Next the board is pushed forward until the line run previously is under the ruler in its initial position, (see Figs. 4 and 6,) after which the latter is pulled out again and another line is marked. Means may be provided for holding positively the marking-ruler while the division-line is run.. I consider, however,

" .that aY mere frictional hold is sufficient and assist the liand to hold this latter until the marking-linev is run. For defining lengths of the pieces marked off thus as to width I provide a scale 25, divided so as to show the same graduations as the drum and the lower v edge of which runs down close to the board to facilitate the marking of lengths as taken off from said scale and transferred onto the board. This lower edge also serves as a gage and defines the position into which one of the longitudinal edges of the board has to be placed at the beginning of operations. At that time this lower edge, the particular edge of the board, and the marking-guide 16, when in its normal position with the measuring-drum at Zero, come all together, as shown in Figs. 1 and 3. This placing of the board may be aided by an adjustable stop 20. To mark these lengths no means are provided to guide the hand and marking implement, since the lines running acrossthe width of the board, or a part of the width as marked od, are only of limited lengths and may be readily drawn by placing the pencil on the board opposite theparticular graduation on scale 25 and running the line across. Furthermore, the devices on the sawtable, upon which such board is placed later on when ready to be cut up, will cause such cut to be straight after started at the proper place. However, in most cases one of the lines (the one at the left end) ymay be run aided by a guide, since the left one of arms 17 is available for such purpose.

To prevent confusion and to facilitate quick reading of the dimensions, as shown by the face of the drum, the larger part of this face is covered by an inclosure or hood 26, and for which inclosure scale 25 may serve as a part, a narrow slot or opening 27 being left for observation.

When the material handled is always of the same thickness, no vertical adjustment of any of the parts of the device is required and the boards may be supported at a fixed height with respect to the marking guide above. Such is rarely the case, however, and it is therefore preferable to have a certain vertical adjustment to provide for the usual thicknesses of lumber and also for any irregularities caused, for instance, by warping, so that this upper surface of the board may always be brought close under the marking-guide, but permits a free operation of this latter over and across the board. This adjustment is obtained by supporting-base 12, which carries the lumber-table 10, in a manner to be vertically adj ustablev with reference to the marking and measuring device. Various mechanical contrivances may be used for such purpose. As shown, the under side of base 12 is provided with iixedly-attached screws 28 and supported by being seated in nuts 29, free to rotate in fixedly-located bearings 31. The outer edges of these nuts are constructed to form worm wheels 32, all engaged by worms 33. By simultaneously rotating all l these worms the-nuts will act upon the screws IOO IlO

tion of any possible defects in the surfaceand, according to the direction `of rotation, base 12 with the table -andlumber on it will be eitherraised or lowered. For such simultaneous rotation of all the worms a system of shafting 34 and bevel-wheels 35 is used, the arrangement being readily understood and all of which are operated by a handle or handwheel 36. Bearings 31, which support the means on which base 12 rests, may form part of or rest on the general frame of the machine.

In the first manner of Vusing the machine, where the marking-lines are to be placed according to certain sizes given, the markingguide 16 is simply pulled out over the board until the figure on the drum appearing through observation-opening'27 shows the desired width. Thus assuming a piece were to be marked off to be subsequently sawed to .a size four inches Wide and thirty six inches long,"the 'board is placed in a position as shown in Figs. 2 and 3,l one of its longitudinal edges resting against lip 15 while the other, by means of the adjustable-table, is-

caused to come right under the edge of scale 25, and the marking-edge of member 16 would be right above such edge and against scale 25. Drum 22 is at zero. The marking-guide is now pulled out until the drum indicates four inches, at which time the guide is in a position four inches fromthe edge of the board and as shown in Figs. Il and 5 and in dotted lines in Fig. 2. To mark the length, the pencil is placed opposite thegraduation showing th irty-six inches on the scale and a line is run over from this latter to meet the longitudinal line `first marked. Assuming now another piece to be marked off five inches Wide and the same or any other length, the board, by means of the movable table on which it rests and without changing the position thereon, is run ahead in and under the measuring-drum until the line first marked is even vwith scale (See Figs. Lland 6.) Marking-guide 16 is next manipulated until the drum shows five inches, (see Fig. 6,) which would mean that the marking guide is in a position where another longitudinal marking-line may be run five inches away from the line run first. In the other manner of using my machine the position of marking-guide 16 is determined with regard to the condition of the material to be marked off and as to the posithereof. Thus in the more special use for which this device is designed the markingguide is primarily placed with regard to the in Fig. He may now mark the line down; For marking the next piece he proceeds as described before and shown in Fig. --that is, the board supported on table 10is rolled the next line is run, with the exception,however, that if the defective portion is not to be made use of a new line is run first on the other side of the defect or knot-hole, so that -in Vfirst to the previously-marked line ,before this latter comes between two lines, which material is to be wasted, and the width of the next piece is then taken from this new line.

vThus while in the first instance the operator pays no attention to sizes at all and merely places the marking-guide with regard to defects he nevertheless considers the size after that, especially as to len gththat is, he runs the marking-line defining length according to a size which he can best make use of. In

order to show these sizes to the operator" at a devices, is prepared for reading by the operator-say, for instance, at three inches Wide pieces are wanted eighteen and thirty inches long, in which case pegs would be inserted in the sockets opposite eighteen and thirty, as shown by scale 25 and with the graduation showing three inches on drum 22.

If pieces are wanted four inches wide and thirty-six inches long, a peg is placed in the particular socket, and so on until the entire face of the drum is more or less filled up' The operator now in manipulating marking-l guide 16 pays attention to the knot-holes, but also watches for pegs to appear in the observation-opening 27, and therefore, while. he places said guide to clear defects, he also places it to the most practical advantage with regard to sizes wanted and as they are indicated by the pegs appearing in the observation-opening. After these preliminaries are all considered he finally marks length as indicated by the peg with reference to scale 25.

. While this description indicates the uses in general outline merely, it is not possible, considering the many possibilitiesy and contingencies arising from location of defects and combination of sizes, to explain all the possible uses to which the device may be put; but it may be added in general that subject to the size-limits of the machine the possibilities of use are practically endless and provide for all possible results which may be expected from such a machine.

Reversions of position and motion are possible without departing from the operative principle of the device. For instance, instead of adjusting the position of the board with reference to the marking and measuring device the same may remain stationary and these latter parts might b e m oved horizontally or vertically.

i Stops 2O are particularly useful when the edges of the board are not parallel, in which i case the first or advancing edge, which must IOC be parallel to the drum and measuring-guide, is placed against these stops. After once placed these stops are moved out of the way, the board by reason of its weight readily remaining in position. In such case lip 15 is of no practical use.
